A cPanel alternative for Windows Server and IIS

Why people search for cPanel on Windows#

cPanel & WHM installs on AlmaLinux OS, CloudLinux, Rocky Linux and Ubuntu, according to its own system requirements. There is no Windows build. Yet the search keeps coming, from two kinds of people.

Hosting companies with a Linux fleet in WHM get customers who need ASP.NET, SQL Server or an application certified only on Windows. They want those few servers to feel like the rest of the business, not like a separate world run through Remote Desktop and IIS Manager.

Website owners and agencies who learned hosting in cPanel move to a Windows plan and look for the same tiles: File Manager, Email Accounts, MySQL Databases, Backups, SSL/TLS. They want to find things where they expect them.

A cPanel alternative for Windows has to satisfy both: an operator panel that works the way WHM does, and a customer panel that a cPanel user can find their way around in a few minutes.

What a good cPanel alternative for Windows has to cover#

Before comparing products, list what your Windows servers must do. In our experience it comes down to seven things:

1. Three levels of access: you, your resellers, and their customers, each with their own panel.
2. Plans as templates: limits and permissions defined once and applied to many accounts.
3. Account isolation: one customer can never read another's files or crash their sites.
4. Resource limits: one busy site cannot starve the server.
5. Self-service: customers manage their own mail, databases, certificates and backups.
6. Automation: an API so your billing system creates and suspends accounts.
7. Safe backups and moves: scheduled off-server backups and a way to bring accounts in.

StackRegent was designed around that list for Windows Server 2016, 2019, 2022 and 2025. The StackRegent vs cPanel page maps each WHM term to its StackRegent equivalent; this page looks at what it is like to work with day to day.

A day in the administrator panel#

Mornings in WHM often start with the account list and the service status page. In StackRegent the Home dashboard is the starting point, with customers, resellers, subscriptions and domains a click away. Monitoring draws graphs every minute and emails you when a value stays high or a service stops. Services Management starts, stops and restarts Windows services, and the Advisor rates the server's configuration and offers one-click fixes.

When something breaks, Diagnose & Repair checks the installation, services, IIS, mail, DNS, databases and NTFS permissions, and fixes what it can. Global search finds a customer, domain or mailbox from any page. Log in as opens a customer's or reseller's panel exactly as they see it, which shortens support tickets considerably.

For bulk work there is a REST API that covers every panel action, described in OpenAPI 3, and the stackregent.exe command line on the server. API keys act exactly as the administrator, reseller or customer who created them, so a reseller's key can only touch that reseller's customers. The Event Manager runs your own commands when panel events happen, much like WHM hooks.

What customers see#

The customer panel opens on Home, with Websites & Domains, WordPress, My Mailbox, Users and Account in the main menu. Inside a subscription they find File Manager, FTP, Mail, Databases with a SQL console, Scheduled Tasks, Resources, Statistics, Backups and the website tools. People coming from cPanel recognize most of it immediately; the Windows-specific parts, such as ASP.NET settings, virtual directories and Web Deploy publishing, sit next to the familiar ones.

Business customers rarely share one login. A customer can add users with roles: Domain Administrator, WebMaster, Application User, Accountant and Mail User are built in, and up to 50 custom roles can be defined over areas such as websites, files, mail, databases, DNS, statistics and backups. A mailbox-only user can sign in to manage their own mail without touching the website.

The panel offers light, dark and system themes and language packs, and you can brand it with your own title, logo, favicon and login background. Resellers can apply their own branding for their customers.

Licensing that feels familiar#

cPanel prices its licenses by the number of accounts on the server, which hosting companies are used to budgeting for. StackRegent does the same: plans differ only in the number of hosting accounts, every plan has every feature, and domains, mailboxes and databases inside an account are unlimited. The largest plan has no account limit and no per-account charge above it. See the pricing page for current plans.

Bringing accounts over#

If your Windows servers run Plesk today, the move is straightforward: StackRegent migrates live from Plesk for Windows and restores Plesk backups, and customers keep their passwords. See the migration page.

If the accounts live on cPanel, StackRegent cannot import cPanel backups. In practice those sites are usually Linux workloads that should stay where they are; the accounts that move to Windows tend to be new .NET or SQL Server projects, or sites rebuilt for IIS. For those, you create the subscription in StackRegent and publish with Web Deploy, Git or FTP.

When StackRegent is the wrong answer#

If a site is PHP on Apache with no Windows dependency, moving it to IIS mostly creates work: .htaccess rules have to become web.config rules, and Linux-specific extensions may not exist on Windows. Keep those sites on Linux. StackRegent is for the workloads that need Windows, run by people who like the way WHM organizes hosting.

Try it alongside your WHM servers#

Install the free trial on a spare Windows Server, rebuild your most common WHM package as a service plan, create a reseller and a customer, and log in as each. Ten days and three accounts are enough to see whether your team and your customers find their way around.
